Description

Technical Field

[0001] The utility model mainly relates to the technical field of electric power meters, in particular to a snap-on sliding installation structure for a digital voltage and current meter. Background Art

[0002] Traditional installation methods for digital voltage and current meters present significant limitations. For one thing, the vastly different sizes of meters make existing mounting structures difficult to adapt to, often requiring custom mounting hardware tailored to specific dimensions. This increases equipment procurement and management costs and reduces on-site installation and commissioning efficiency. Furthermore, conventional mounting structures often utilize fixed connections such as bolt fastening. When meters require repair or replacement, disassembly is cumbersome and requires tools to gradually loosen bolts, which is time-consuming and impacts timely maintenance.

[0003] Although some snap-on mounting structures simplify assembly and disassembly to a certain extent, the coordination between the snaps and the mounting plate lacks precise guidance and stable limiting, and there is a risk of loosening or falling off when tightening. In addition, the spacing between the snaps cannot be flexibly adjusted, making it difficult to adapt to diverse instrument installation needs and unable to meet the industrial site's requirements for "flexible adaptation, convenient assembly and disassembly, and stable and reliable" installation structures.

[0004] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0005] 1. Technical problems to be solved by the utility model:

[0006] The utility model provides a snap-on sliding installation structure for a digital voltage and current meter, which is used to solve the technical problems existing in the above-mentioned background technology.

[0007] 2. Technical solution:

[0008] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a snap-on sliding mounting structure of a digital voltage and ammeter, comprising an instrument box body, an instrument back cover and a mounting structure, the mounting structure comprising two snaps, a press-type connector and a mounting plate; wherein, the snap includes a top plate and two elastic arms extending downward from both sides of the top plate, a positioning hole is provided on the top plate, and hook-shaped ends are provided on the inner sides of the two elastic arms, the press-type connector comprises a threaded sleeve, a compression spring and a pressing rod are provided in the threaded sleeve, the threaded sleeve is sleeved on the pressing rod, the pressing rod is slidably connected along the inner wall of the threaded sleeve, the mounting plate is embedded in the snap, the inner wall of the elastic arm is arranged close to the mounting plate, and a sliding groove and a mounting hole are provided on the mounting plate.

[0009] Furthermore, the elastic arm is in an inwardly bent shape, and a slot is provided on the outer side thereof, and the end of the elastic arm passes through the slot.

[0010] Furthermore, the hook-shaped end portion, the elastic arm and the top flat plate are an integrally formed structure, and there is a certain distance between the two hook-shaped end portions.

[0011] Furthermore, the instrument back cover is fixedly connected to the instrument box body by screws, and a plurality of positioning holes 2 are opened on the instrument back cover, and the positioning holes 2 are arranged corresponding to the positions of the positioning holes 1 and the sliding grooves.

[0012] Furthermore, the threaded sleeve is threadedly connected to the first positioning hole and the second positioning hole respectively, and a hexagonal nut is welded to one end of the threaded sleeve.

[0013] Furthermore, the pressing rod includes a rod body, a limiting boss, a pressure head and a pressing end, and the pressure head and the pressing end are respectively located at two ends of the rod body.

[0014] Furthermore, the sliding groove passes through the mounting plate, and the end of the threaded sleeve and the pressure head are both located in the sliding groove.

[0015] 3.Beneficial effects:

[0016] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0017] The sliding groove on the mounting plate provides space for the clips to move, and the distance between the two clips can be flexibly adjusted to accommodate digital voltage and current meters of different widths. This eliminates the need for separate mounting structures for meters of different sizes, significantly improving on-site installation efficiency while reducing costs and effectively resolving the poor adaptability of traditional installation methods.

[0018] The push-type connector works in conjunction with the buckle. Pressing the push rod downward expands the buckle's elastic arm, quickly releasing the buckle from the mounting plate. When tightening, the elastic arm and the inclined side wall of the mounting plate press against each other, providing a secure and reliable connection. Compared to traditional bolt disassembly and assembly, no additional tools are required, simplifying the operation process and significantly reducing instrument disassembly and assembly time. This makes daily inspection and replacement easier, improving equipment maintenance convenience.

[0019] The hook-shaped end of the clip, the elastic arm, and the top flat plate are integrally formed, providing high structural strength. The outer slot of the elastic arm provides a precise path for its end to extend and retract, and the upper limit boss of the pressing rod restricts the movement path, ensuring stable and controllable tightening and loosening of the clip. The threaded connection between the threaded sleeve and the positioning hole, and the locking screws fixing the mounting plate to the equipment, further enhance the overall structural stability, ensuring that the digital voltage and ammeter will not loosen or fall off after installation, thereby improving its reliability.

[0020] This mounting structure integrates functions such as spacing adjustment, quick disassembly and assembly, and stable clamping. It uses simple components to meet the diverse installation needs of digital voltage and ammeters, reduce the use of additional auxiliary components, optimize the complexity of the installation structure, and facilitate its promotion and application in various equipment scenarios where digital voltage and ammeters need to be installed.

[0021] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and are the same as the existing technology or can be implemented by using the existing technology, so they are not described in detail here.

[0034] Refer to the attached Figure 1-6 , a digital display voltage and ammeter snap-on sliding mounting structure, including an instrument box body 1, an instrument back cover 2 and a mounting structure, the mounting structure including two snaps 3, a press-type connector 4 and a mounting plate 5; wherein the snap 3 includes a top flat plate 301 and two elastic arms 302 extending downward from both sides of the top flat plate 301, a positioning hole 303 is opened on the top flat plate 301, and hook-shaped ends 304 are provided on the inner sides of the two elastic arms 302, the press-type connector 4 includes a threaded sleeve 401, a compression spring 402 and a pressing rod 403 are provided in the threaded sleeve 401, the threaded sleeve 401 is sleeved on the pressing rod 403, the pressing rod 403 is slidably connected along the inner wall of the threaded sleeve 401, the mounting plate 5 is embedded in the snap 3, the inner wall of the elastic arm 302 is set close to the mounting plate 5, and the mounting plate 5 is provided with a sliding groove 501 and a mounting hole 502.

[0035] The instrument back cover 2 and the instrument box body 1 are fixedly connected by screws, and together they constitute the basic load-bearing components of the instrument; the mounting structure, as the core assembly component, includes two clips 3, a press-type connector 4 and a mounting plate 5. Through the coordinated action of various components, flexible installation and quick disassembly of the instrument can be achieved.

[0036] The buckle 3 includes a top plate 301 and two elastic arms 302 extending downward from both sides of the top plate 301. A positioning hole 303 is provided on the top plate 301 to provide a basis for cooperation with the press-type connector 4. The inner sides of the two elastic arms 302 are provided with hook-shaped ends 304. The hook-shaped ends 304, the elastic arms 302 and the top plate 301 are an integrally formed structure, and there is a certain distance between the two hook-shaped ends 304. The distance cooperates with the press-type connector 4 to realize the clamping or loosening action of the buckle 3 and the mounting plate 5.

[0037] The elastic arm 302 is bent inward, and a slot 3021 is provided on its outer side. The end of the elastic arm 302 passes through the slot 3021. During the operation of the buckle 3, the slot 3021 provides a telescopic path for the end of the elastic arm 302: when it is necessary to loosen the buckle 3 and the mounting plate 5, the elastic arm 302 is squeezed outward by the press-type connector 4, and its end inserted into the slot 3021 is squeezed and extends outward along the slot 3021, so that the elastic arm 302 is stretched outward as a whole, and a certain gap is generated between it and the mounting plate 5; in the clamped state, the elastic arm 302 is reset and the end moves back.

[0038] The mounting plate 5 is embedded in the buckle 3, and the inner wall of the elastic arm 302 is set close to the mounting plate 5. When in the clamped state, the inner wall of the elastic arm 302 and the inclined side wall of the mounting plate 5 are pressed against each other to ensure that the buckle 3 firmly holds the mounting plate 5.

[0039] The push-type connector 4 includes a threaded sleeve 401, a compression spring 402, and a push rod 403. The threaded sleeve 401 is sleeved on the push rod 403, and the push rod 403 slides along the inner wall of the threaded sleeve 401. The push rod 403 includes a rod body 4031, a limiting boss 4032, a pressing head 4033, and a pressing end 4034. The pressing head 4033 and the pressing end 4034 are respectively located at the two ends of the rod body 4031.

[0040] In actual operation, the principle of the press-type connector 4 to realize the tightening and loosening function of the buckle 3 is as follows: when it is necessary to loosen the buckle 3 and the mounting plate 5, the pressing rod 403 is pressed down, and the pressure head 4033 extends into the middle of the two hook-shaped ends 304, pushing the two hook-shaped ends 304 outward, driving the elastic arm 302 to stretch outward, and completing the loosening action; after the pressure is released, the compression spring 402 acts on the pressing rod 403 to achieve automatic reset, and the limiting boss 4032 on the pressing rod 403 can limit the movement path of the rod body 4031 in the threaded sleeve 401, avoiding excessive pressing or abnormal reset.

[0041] The threaded sleeve 401 is threadedly connected to the positioning hole 201 of the instrument back cover 2 and the positioning hole 1 303 of the top flat plate 301 of the buckle 3 respectively. A hexagonal nut 404 is welded to one end of the threaded sleeve 401. By screwing in the threaded sleeve 401, a stable connection between the instrument back cover 2 and the buckle 3 is achieved, providing an assembly basis for the entire installation structure.

[0042] The mounting plate 5 is provided with a sliding groove 501 and mounting holes 502. The sliding groove 501 extends through the mounting plate 5. The end of the threaded sleeve 401 and the pressure head 4033 are both located within the sliding groove 501. The sliding groove 501 provides space for the clips 3 to move, allowing for adjustment of the spacing between the clips 3 to accommodate instruments of varying widths and enhance installation flexibility. The mounting plate 5 is screwed into the mounting holes 502 at both ends via locking screws, securing it to the device and ensuring a stable assembly of the entire mounting structure.

[0043] In this embodiment, the steps for using the snap-on sliding installation structure of the digital voltage and current meter are as follows:

[0044] Place the mounting plate 5 at the device installation location, screw the locking screws into the mounting holes 502 at both ends of the mounting plate 5, and firmly connect the mounting plate 5 to the device to provide basic support for subsequent instrument installation.

[0045] Threaded sleeve assembly: Take the threaded sleeve 401 of the push-type connector 4, screw one end with the hexagonal nut 404 welded to it into the second positioning hole 201 of the instrument back cover 2, and then continue to screw it into the first positioning hole 303 of the top flat plate 301 of the buckle 3. Through the threaded connection, the initial assembly of the instrument back cover 2 and the buckle 3 is completed, so that the two form a connected whole;

[0046] Adjustment of the spacing between the buckles: Since the sliding groove 501 on the mounting plate 5 provides space for the buckles 3 to move, the buckles 3 can be pushed to slide along the sliding groove 501. The spacing between the two buckles 3 can be adjusted according to the width of the meter to adapt to the size of the meter and meet the installation requirements of meters of different specifications.

[0047] Fasten the mounting plate with the buckle: Align the buckle 3 with the mounting plate 5 and insert it. At this time, the inner wall of the elastic arm 302 is in close contact with the mounting plate 5, and the hook-shaped end 304 inside the elastic arm 302 cooperates with the mounting plate 5. In the fastened state, the inner wall of the elastic arm 302 and the inclined side wall of the mounting plate 5 are pressed against each other, so that the buckle 3 firmly holds the mounting plate 5. The instrument is connected to the buckle 3 through the back cover 2, and the instrument installation and positioning is preliminarily completed;

[0048] Align the instrument box body 1 with the instrument back cover 2 that has been assembled with the snap 3 and press-type connector 4, and use screws to securely connect the instrument box body 1 and the instrument back cover 2 to form a complete closed structure and ensure the normal working environment of the instrument;

[0049] If the instrument needs to be disassembled, the pressing end 4034 of the pressing connector 4 can be pressed down, and the pressure head 4033 of the pressing rod 403 can be extended into the middle of the two hook-shaped ends 304, pushing the two hook-shaped ends 304 outward, driving the elastic arm 302 to be stretched outward, and the end of the elastic arm 302 can be extended outward along the card slot 3021, and the buckle 3 and the mounting plate 5 are loosened; at this time, the buckle 3 can be pushed to move along the sliding slot 501, or the connecting assembly of the instrument box body 1 and the instrument back cover 2 can be directly removed to complete the disassembly of the instrument, which is convenient for maintenance, replacement and other operations.

[0050] To sum up, the entire usage process, through the coordinated cooperation of the snap 3, the press-type connector 4, the mounting plate 5, the instrument box body 1, and the instrument back cover 2, not only meets the flexible adaptation requirements for the installation of instruments of different sizes, but also realizes the convenience of quick disassembly, thereby improving the convenience of operation and adaptability.

[0051] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
